Self-cleaning effect in an all-fiber spatiotemporal mode-locked laser based on graded-index multimode fiber
نویسندگان
چکیده
We demonstrate an all-fiber spatiotemporal mode-locked laser based on graded-index multimode fiber. Due to the high damage threshold of fiber devices, output single-pulse energy reach up 11.67 nJ. The beam quality at state is significantly improved compared with continuous wave as a result self-cleaning effect. By amplifying pulse in amplifier, power pulses can be obtained system MMFs.

Spatiotemporal mode-locking in multimode fiber lasers.
A laser is based on the electromagnetic modes of its resonator, which provides the feedback required for oscillation. Enormous progress has been made toward controlling the interactions of longitudinal modes in lasers with a single transverse mode. For example, the field of ultrafast science has been built on lasers that lock many longitudinal modes together to form ultrashort light pulses. How...
متن کاملMode-locked fiber laser gyroscope.
We propose and demonstrate a novel fiber-optic gyroscope in the form of a mode-locked laser consisting of a laser cavity formed by a planar mirror at one end, a gain medium, and a Sagnac interferometer at the other end. The Sagnac interferometer serves as a reflector as well as a rotation-sensing element. The output of the gyroscope is a series of short optical pulses. The separation of two set...
متن کاملSpectrum-, pulsewidth-, and wavelength-switchable all-fiber mode-locked Yb laser with fiber based birefringent filter.
We examined methods of controlling the pulse duration, spectral width and wavelength of the output from an all-fiber Yb laser mode-locked by carbon nanotubes. It is shown that a segment of polarization maintaining (PM) fiber inserted into a standard single mode fiber based laser cavity can function as a spectral selective filter. Adjustment of the length of the PM fiber from 1 to 2 m led to a c...
متن کاملNonlinear beam self-cleaning in a coupled cavity composite laser based on multimode fiber.
We study a coupled cavity laser configuration where a passively Q-switched Nd:YAG microchip laser is combined with an extended cavity, including a doped multimode fiber. For appropriate coupling levels with the extended cavity, we observed that beam self-cleaning was induced in the multimode fiber thanks to nonlinear modal coupling, leading to a quasi-single mode laser output. In the regime of ...
متن کاملWidely tunable Tm-doped mode-locked all-fiber laser
We demonstrated a widely tunable Tm-doped mode-locked all-fiber laser, with the widest tunable range of 136 nm, from 1842 to 1978 nm. Nonlinear polarization evolution (NPE) technique is employed to enable mode-locking and the wavelength-tunable operation. The widely tunable range attributes to the NPE-induced transmission modulation and bidirectional pumping mechanism. Such kind of tunable mode...
